i noticed that odrive only use one SPI (master), but if i wanna use two SPI-type encoder, is the speed enough?
or all type sensors use ABI interface when motor run normally, only read abs angle value via SPI when cold boot? (to avoid re-calib ) ?
The speed is enough for two SPI, but you need tri-state buffers usually (or differential signalling). You can, in theory, use abs cold boot → ABI run, but it has to be done manually.
thank thee very much!
